I was thinking the same! however this is my latest idea,
The principle is to allow the bi - directional pump a feed of water and also so stop any water pressure building up unnecessarily.
Water enters the scoop fitted on the bottom of the hull, near the transom, which then goes through the stop cock, then through a non return valve. this is so that water is always flowing in one direction, so when emptying the ballast air + water is not going to be forced under. plus i doubt any ballast pjmp would be able to push against the flow under speed.
It then goes to the tee for the pump, and then through the upper valve. this stops the backflow of water at low speeds and allows the pump to suck only water from the scoop.
Just had an idea - this system would work very well with a leg shower, as there shoud be water being constantly flowing at speed!
So there you have it, minimal pressure on the ballast pump yet water on demand at all times!
